The actress on what's in store for the milestone 20th season and for Olivia Benson.

"Last season, we saw Rollins at her her harshest, most judgmental self in a confrontation with a prostitute," Giddish explains. "We learned the reason behind [the confrontation] was her boyfriend, [Dr. Al Pollack], who'd been sneaking in quite a few visits with escorts on the side."

In the photo below, which features a scene from the season premiere, the actress reveals, "Rollins needs to speak her mind to Al and calls him for lunch. But it's a short meeting: She returns from the bathroom to catch him flirting with a waitress!"
